Why Do You Need Caching Plugin?
WordPress is a well optimized platform for website development and there are ways to further improve its performance. As you add more elements, such as themes, widgets, high-resolution images and others, your website’s loading time will increase affecting user experience. If your website doesn’t show the meaningful and readable content in three seconds, people will start to click the back button on the browser or close the tab.
WordPress is based on PHP scripting, which requires server-side processing. If there are hundreds of people who access your website at once, the performance will suffer. So it is necessary to speedup your WordPress site to retain the users on your site. Caching plugin is a good way to ensure that your website will load faster. After installing caching plugin, it will generate static HTML pages, which will be saved on the server.
Caching plugin renders PHP scripts into much simpler static HTML page that can be transferred to your browser, without any kind of server-side processing. So try out one of the WordPress caching plugin and improve the page loading time of your site.
